VALVE-BAG.

Patented Nov. 21, 1916.

Application filed May 17, 1915. Serial No. 28,544.

To all whom it may concern.

Be it. known that I, Annmmn M. Barns, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented acertain new and useful Improvement in Valve-Bags, of which the following is a specification.

My invention relates to valve bags provided with handles. and has for its object to provide such a valved bag with a handle so that it may be manipulated at'all times, .and particularly after the bag has been filled.

It is illustrated in the accompanying drawings wherein Figure 1 is a side elevation of a valve bag with the handle shown partly in dotted lines and the bag collapsed.- Fig. 2 is an edge view'of the collapsed bag with the valve distended for the admission of the filling tube. Fig. 3 is a cross section on the line 3-3 of Fig. 1 with the valve distended and the filling tube inserted.

Like parts are indicated by the same letter in all the figures.

A, A, are the sides of the bag.

B is the valve opening.

C is the bottom of the bag which his normally folded fiat against the side of the bag,

F is an inside handle member preferably consisting of a flat surfaced strip placed longitudinally .and parallel with the axis of the valve opening and a little at one side I of the midoqe line of the top of the bag,

and against he inner surface of the top of the bag.

G is the exterior handle portion, which ,in this case is shown as made of heavy may be applied to any kind ofa bag, or

bag of any kind of material.

I have illustrated the invention here in COIIIIQCtlOIl with the use of a paper cement bag with satchel ends, one open to form the valve. and with a handle consisting of an mt erior wooden member and an exterior twine member, the two secured together by staples which pass through the fabric of the bag.

The handle must be inserted through the valve opening, and since the filling tube J must also be inserted through the opening, the arrangement must'be such that the inner handle portion will be at one side of the filling tube axis, so that the tube or the a stream of material can pass the inner handle portion and not be obstructed thereby.

The use and operation of my invention are as follows:When the valve bag is completed, that is, closed at one end and provided with a small filling tube at the other end, the handle is applied by inserting the inner handle member through the valved opening, and preferably at one side thereof, and bringing it into proper position on an interior anvil which carries it and by which it is inserted in the bag. The exterior handle portion is then placed in proper position, and the two are united by staples, one for each end of the inner handle portion to give length to the'loop and width to the grip on the bag, and another through the overlapped portions of the twine, and preferably near the middle of the inner member.

The essential features of this particular form of handle are as follows: An extended inner handle member is applied to the inside of the heavy end portion of the bag, being passed in through the valve opening and placed preferably at one side of the same or away from the center of the opening so as to leave room for the filling tube to slip past the inner handle portion. The handle comprises a loose, soft flexible member outside of the bag, which therefore assumes any desired position, and permits the bags to be folded or laid one on another without injury to either. I

It will be understood that the usual type of filling tube such as used to fill a bag of this kind is more or less pointed or sloped at the forward end, being out under ordinary circumstances something like the quill of the old fashioned quill pen. It is necessary, therefore, to have the block only slightly to one side So that it willnot catch eonsisting of a hag lau prorided with a valve opening at one corner of one end, and

a handle eo1nprisi1n a longitudinally extended inner portion in line with but at one side of the axis ol the valve opening, a lleXihle exterior portion, and staples whereby the two portions are serured together through the fabric of the bag.

2. It handled hag eonsistine' ot' a bag rlosed at both ends hut provided with a valve opening at one corner of one end, and a handle comprising a longitudinally ex tended inner portion in line with but at one side of the axis of the valve opening, a flexihle exterior portion in the form of a loop terior portion loeated within the valve in line with said opening and parallel with the handle and extending through the entire length of the handle and means passing through the wall otthe hag adjacent with the end ol sueh rigid portion and the handle to hold them together.

In testin'iony whereof I altix 1n v signature in the presence of two witnesses this 14th day of May, 1915.
